What is a Sprain?
A sprain is a stretch and/or tear of a ligament (fibrous band of connective tissue that joins bone to bone). Every joint in the body is stabilized and supported by a ligament. They help control range of motion and enabling us to complete simple tasks such as walk and run.
What is a Strain?
A strain is an injury of a muscle and/or tendon. Tendons (fibrous cords of tissue that attach muscles to bone).
Sprains and strains are among the most common injuries in sports, professional, amateur athletes and the general public. You are more at risk for the injury if you have a history of sprains and strains, are overweight, and are in poor physical condition.
Sprains and strains are categorizes according to severity:
- MILD - A ligament or muscle is stretched in a mild sprain, but there is no joint loosening.
- MODERATE - A moderate sprain partially tears the ligament or muscle, producing joint instability, and some swelling.
- SEVERE - A severe sprain produces excruciating pain at the moment of injury, as ligaments or muscle tear completely, or separate from the bone. A complete rupture makes the joint nonfunctional and will generally require some form of surgery.
You should seek medical attention if you can't walk more than four steps without pain, can't move the affected joint and you have numbness in any part of the injured area.
What are the signs of a sprain?
While the intensity varies, pain, bruising, swelling, limited ability to move the affected joint, and inflammation are common to all three categories of sprains: mild, moderate, and severe. You may feel a tearing or hear a 'pop' sound in the joint.
What causes sprains?
A sprain is caused by direct or indirect trauma (a fall, a blow to the body, etc.) that knocks a joint out of position, and overstretches, and, in severe cases, ruptures the supporting ligaments. This injury occurs when an a person lands on an outstretched arm; slides into a base; jumps up and lands on the side of the foot; or runs on an uneven surface.
What are the signs of a strain?
Signs include pain, muscle spasm, muscle weakness, swelling, inflammation, limited ability to move the affected muscle, and cramping. With a mild strain, the muscle/tendon is stretched or pulled, slightly. Some muscle function will be lost with a moderate strain, where the muscle/tendon is overstretched and slightly torn. In severe strains, the muscle and/or tendon is partially or completely ruptured, often disabling the person.
- Achilles tendon strain. Pain along the back of your foot and above your heel, especially when stretching your ankle or standing on your toes. Most strains are mild. The seriousness of the strain will affect your walking. Suddenly increase your activity or warm up improperly can cause an Achilles tendon strain. Trying to go fast, jumping (hurdles), cutting (football) or twisting in the air are just some of the scenarios where you could develop Achilles tendon strain.

- Back strain. When the muscles that support the spine are twisted, pulled, or torn, the result is a back strain. Athletes who engage in a lot jumping (during basketball, volleyball, etc.) are at risk to this injury. Everyday activities can lead to back strain, pickup a heavy item and twisting at the same time as in loading groceries into the car, carrying laundry up stair and turning too quickly.
- Hamstring muscle strain. A hamstring muscle strain is a tear or stretch of a major muscle in the back of the thigh. The injury can sideline a person for up to six months. The likely cause is muscle strength imbalance between the hamstrings and the muscles in the front of the thigh, the quadriceps. Kicking a football, running, or leaping to make a basket can pull a hamstring. Hamstring injuries tend to recur.
- Quadricep strain. Muscle strain in the front thigh (quadriceps muscles in the front, and the adductor muscles on the inside.). The hamstring and quadriceps muscle groups are particularly at risk for muscle strains because they cross both the hip and knee joints. They are also used for high-speed activities, such as track and field events (running, hurdles, long jump), football, basketball, and soccer.
- Calf strain. Stretches, tears, or incomplete ruptures of the large calf muscles (gastrocnemius). Also called 'Tennis leg' happens when lunging or pushing off one leg to get to a wide ball or serve. May also happen with daily activities, such as running to catch a bus or climbing stairs. It feels like being kicked in the leg from behind. The tennis leg sufferer feels an quick severe sharp pain, turns around to see who kicked them, only to discover that no one is there. To read more indepth about Tennis leg
- Elbow strain. A strain is when a muscle becomes overstretched and tears. This painful injury, also called a "pulled muscle," can be caused by an accident, improper use of a muscle, or overuse of a muscle. Frequently occur in racquet, throwing, and contact sports.
- Shoulder strain. Your shoulders are the most movable joints in your body. Overuse, repetitive motion or an unnatural twisting of the shoulder are causes of shoulder strain. Quite often the due to swelling, which can make almost any movement in the cavity of the shoulder joint both difficult and uncomfortable.
- Hand strain. Repetitive strain injuries are linked with work related usage of the hands. A tight grip or squeezing the hand overstretches the hand muscles. Women are at high risk as 'standard' hand tools are often too large, too wide or too slippery. Sports such as gymnastics, tennis, rowing, golf-sports that require extensive gripping-have a high rate of injury.
- Neck strain. Not considered a serious injury, but there is pain and dysfunction of the neck. The causes are too much time in an awkward position (hunched over a steering wheel while driving, hunched forward to view a computer monitor, or cradling a phone in the crook of the neck). Sleeping in a position that strains the neck, such as with a pillow that is too high or too firm. Carrying a heavy suitcase or other object on one side of the body.
Conservative Treatment Options for Strains and Sprains
In cases of mild and moderate sprains and strains, your physician will usually recommend conservative treatment options (click to view). In severe cases, surgery may be undertaken after which you will enter a period of surgical recovery. click here to view more information about surgical recovery.
